Answer:
Because it was sand in the seawater sample
Explanation:
By the evaporation method you put the seawater in a boiler so that all the water evaporates from the jar, after that, as the salt is a heaver compound it doesn't evaporates and because of this you can weight the amount of salt that is left. If in the initial sample you also have sand this weight will interfier with the amount of salt that is cuantified when you weight it and because of this the salinity results will be incorrect.
Answer:
Set of electromagnetic radiation.
Explanation:
The electromagnetic spectrum is the energetic distribution of the set of electromagnetic radiation. It consists of <u>electromagnetic waves</u>, which are composed by an electric field and a magnetic field. Every object emits and absorbs these kinds of radiations. This spectrum encompasses from Gamma rays, which are highly energetic electromagnetic waves with high frequency and short wavelength, to Radio waves, which are low energetic electromagnetic waves with low frequency and long wavelength. The visible light, like the sunlight, is only a tiny portion of the electromagnetic spectrum, the rest of the electromagnetic waves are invisible to the human eye, like infrared light, UV light, X-rays, and microwaves, but they can be perceived and be measured with proper filters.
